The motion of molecules and the transfer of energy decreases with increase in volume of the solution.
What is effect of volume in motion of particles?The volume of a solution is inversely proportional to the motion of the molecules of a substance.
An increase in volume results in a decrease in the motion of particles due to a decrease in the frequency of particles and thus, less energy is transferred.
Therefore, the motion of molecules and the transfer of energy decreases with increase in volume of the solution.

The carbon cycle is a process that involves:
A) The creation of carbon atoms
B) Physical Changes for carbon molecules
C) Both B & C
D) All of the above
Answer:
All of the above
Explanation:
Carbon atoms are created during the process of photosynthesis. During this process, plants will absorb carbon dioxide and sunlight to create energy, glucose, and other sugars. And for the physical changes of carbon molecules, carbon can undertake multiple changes overtime. Even though this element can be stored in the Earth for millions of years, it can be transferred in seconds from one object to another
What adverse effects does covering the land with concrete and asphalt create?

Motor vehicle traffic and its accompanying pollution have been a major environmental concern for decades The materials used, primarily asphalt and concrete, negatively impact the environment in three ways. In built areas with extensive impervious surfaces, water can't soak naturally into the earth instead it rushes across the landscape, carrying pollutants and biological contaminants into our waterways, poisoning fish, wildlife, and us.
Which represents the cross between parent plants if one is heterozygous and has yellow-colored pods and the other is homozygous and has green-colored pods? yy ´ yy yy ´ yy yy ´ yy yy ´ yy
The cross between parent plants if one is heterozygous and has yellow-colored pods and the other is purebred and has green-colored pods is Yy×yy.
What is Heterozygous?Heterozygous may be defined as the existence of two distinguishable alleles at a distinct gene locus.
In this condition, Yellow is dominant over green i.e. Y>y. Heterozygous means the existence of two distinguishable alleles at a distinct gene locus. So, the genotype of one parent is Yy, while the other parent is purebred and has green-colored pods. Hence, the genotype is yy.
Therefore, the cross between parent plants if one is heterozygous and has yellow-colored pods and the other is purebred and has green-colored pods is Yy×yy.

A snow-covered mountain has a higher albedo than a dark-colored corn field. Therefore, it will reflect solar energy _____ than the field. (lower, more, less).
A snow-covered mountain has a higher albedo than a dark-colored corn field. Therefore, it will reflect solar energy more than the field.
Does snow have a high or low albedo?Dark surfaces absorb the rays from the sun (low albedo). Ice- and snow-covered areas have high albedo, and the ice-covered Arctic reflects solar radiation which otherwise would be absorbed by the oceans and cause the Earth's surface to heat up.
Why does snow have a high albedo?Freshly fallen snow reflects incoming solar radiation very well and therefore has a high albedo. New snow typically has an albedo of 0.96 to 0.98 in the visible and near-UV range (Grenfell et al., 1994), and 0.8 averaged over the entire wavelength spectrum.

Sperm cells are about to be made from a cell with 66 chromosomes. How many chromosomes will the sperm cells have?
Answer:
33
Explanation:
Gametes (sperm or egg) have half the chromosome of a diploid cell. That's why they are haploid cells.
If chromosomes come from a cell with 66 chromosomes, sperm will have 66/2 = 33.
That's why us humans have 46 chromosomes, but our egg or sperm has only 46/2 = 23 chromosomes.
Answer:
33 chromosomes
Explanation:
The cell undergoes reduction-division to produce 2 daughter cells with equal number of chromosomes. Hence, the sperm cells will have 33 chromosomes.

How does a diploid organism restore its number of chromosomes if meiosis produces haploid cells?
The condition is called diploidy. During meiosis the cell produces gametes, or germ cells, each containing half the normal or somatic number of chromosomes. This condition is called haploidy.
How does meiosis reduce the number of chromosomes from diploid to haploid?The parent cell undergoes one round of DNA replication followed by two Different cycles of nuclear division.
The method results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.

Sayid listed some characteristics of waves in a chart. Part of his chart is shown.
A 1-column table with titled Characteristics of Waves. The column labeled Electromagnetic Waves has entries travel in straight lines, move only through matter, involve interactions with magnetic fields.
Which of these would correct Sayid's error?
Change the heading of the chart to “Mechanical.”
Replace “travel in straight lines” with “move in curved paths.”
Add “move due to particles bumping into each other” to the chart.
Change “move only through matter” to “move through space and matter.”
Answer:
Change “move only through matter” to “move through space and matter.”
Explanation:
Electromagnetic wave like light can travel thru both space and matter. Ever tried to shine a flash light thru a water bottle? The light passes thru the water and the bottle (both are types of matter: liquid and solid) and reaches the other side.
Ever see Suns ray enter your eyes? The light travels thru the vast empty space (our solar system) to reach earth.
Thus, electromagnetic waves can move thru both space and matter.
Electromagnetic waves have the ability to move through matter as well as through space. So the correct option is Option D.
What are the characteristics of Electromagnetic waves?An electromagnetic wave is a type of radiation that travels through space. Electromagnetic waves form when an electric field meets a magnetic field.
Electromagnetic waves do not require molecules to travel. Unlike sound waves, which travel through matter by smashing molecules together, electromagnetic waves cannot travel through a vacuum such as space. Instead, they can travel through the air, solid matter, and even space. This makes electromagnetic waves very useful for many technologies.
There are many different types of waves in the electromagnetic spectrum, ranging from radio waves that are as long as a building to gamma rays that are smaller than a nucleus of an atom.
